05 Jun Ocuco Requests Re-Examination of Seiko “Freeform” Patent

MANCHESTER, Connecticut. Ocuco, Inc., the developer and provider of Innovations lab management software, has filed a request with the U.S. Patent Office, seeking re-examination of Seiko Epson Corp.s Patent 6,019,470, which covers the invention of back-surface progressive lenses. The patent, titled Progressive multifocal lens and manufacturing method of eyeglass lens and progressive multifocal lens, was issued to Seiko Epson on Feb. 1, 2000. Ocuco filed the request, which asks that the patents key claims be re-examined and cancelled on May 21 this year.

A re-examination is an administrative procedure established in the patent regulations that allows any person to request that the Patent Office reconsider its grant of a patent, based on substantial new questions of patentability, which the requester must clearly set out.

I began this inquiry because I was familiar with engineering projects back in the early 1990s at both Gerber Optical and Coburn Optical, which had as their objective the production of back-surface progressives, said Robert Shanbaum, president of Ocuco, Inc. Digging into it, we found that both back-side and dual-sided progressive lenses were anticipated in prior patents, going back to the 1930s. We have enumerated this prior art in our re-examination request, Shanbaum said.

A patent is valid until its not?no one should think that our action in any way invalidates the patent at this point, Shanbaum noted. We hope that our request is sufficiently persuasive that the PTO will grant our request, and then cancel the patent.
